Don't use harsh chemicals on your hair. The shampoo and conditioner you use may be contributing to poor hair growth. Most commercial shampoos contain sulfates, which strip your hair of its natural oils and leave it susceptible to damage.[2] Conditioners contain silicones that coat the hair with chemicals and need to be washed out with more strong shampoo. This cycle is really damaging to hair! Here's what you can do instead:
Give your hair one last wash with a strong shampoo, such as a clarifying shampoo, to get rid of any remaining silicones. Don't condition it this time; just gently detangle it and let it air dry.
Give your hair a break for a few days. Don't do anything to it - don't wash it, straighten it, or use any products.
Next time you wash your hair, use an all-natural shampoo. Read the label and use a shampoo that contains only natural oils and other cleansers, no chemicals. You could even try going shampoo free!
Condition with diluted apple cider vinegar. This really works, and when it dries you won't smell like vinegar at all. For a deep-conditioning treatment, try using coconut oil. You'll never want to go back to the chemical-laden stuff you used before.
